Definitions

  • the invention relates to a synthesis gas heat exchanger system with a synthesis gas radiation cooler, two syngas convection coolers, one Raw gas-pure gas heat exchanger, a raw gas-inert gas heat exchanger and at least one separator or without a synthesis gas radiation cooler.
  • Heat exchanger systems are known in which the Synthesis gas radiation cooler vertical and the Synthesis gas convection cooler, raw gas clean gas and the raw gas-nitrogen heat exchanger is laid horizontally are.
  • This arrangement has the advantage of a small one Height of the installed equipment, but the decisive disadvantage of the risk of growth and clogging of the horizontal heat exchanger tubes and of the connecting lines through the in synthesis gas carried dust and slag particles.
  • the object of the invention is therefore a To create synthesis gas heat exchanger plant whose Self-cleaning of residual particles, dust deposits and other solid particles during hot operation, improved in the start-up phase and when the business is at a standstill is that the mass flows in the individual Heat exchanger trains regulated and that business interruptions and increased maintenance costs can be avoided.
  • the invention prevents the vertical or inclined Arrangement of the heat exchangers also during operation certainly the formation of dust blockages in the Plant resulting from the following vertical or inclined interconnected equipment consists of: Synthesis gas radiation cooler, synthesis gas convection cooler, Raw gas-clean gas heat exchanger, raw gas nitrogen heat exchanger, Separators with mass flow controllers, Sootblowers and special support.
  • soot blower systems provided during operation and after the system is switched off and support the heat exchanger tubes blow dust-free, so that on the one hand during the Early clogging is avoided and on the other hand reliably prevents residual deposits can be.
  • Function and task of the synthesis gas heat exchanger system is a synthesis gas that, for example, at coal gasification occurs from a combustion temperature from approx. 1850 ° C to 1400 ° C to room temperature cool down to the gas one downstream Supply cold gas cleaning.
  • Purification is from the synthesis or raw gas so-called "clean gas", which is used for preheating for further use by the raw gas-clean gas heat exchanger is led and then to a gas turbine or other consumer.
  • Synthesis gas flows through Synthesis gas at a relatively low speed Synthesis gas radiation cooler in the direction of falling Slag.
  • the circulation flow in the boiler tubes is opposite to the gas flow. This leaves at the end of the synthesis gas radiation cooler Synthesis gas e.g. B. over two offset by 180 ° Gas outlet lines the synthesis gas radiation cooler and flows in a vertical or inclined arrangement Syngas convection cooler with its straight line executed heat exchanger tubes.
  • the synthesis gas flows through these pipes from the outside in counterflow are water cooled.
  • the gas / gas heat exchangers are connected, also arranged vertically or inclined (Raw gas-clean gas heat exchanger / raw gas-inert gas heat exchanger). These exchangers also consist of straight tubes that are countercurrent, cocurrent or Cross current are operated.
  • the nitrogen reduces the firing temperature, which the Generation of nitrogen oxides prevented (reduced), likewise it increases the volume flow of the gas, which on the Turbine blades are directed.
  • the two trains of the syngas convection coolers and the raw gas / clean gas and raw gas / inert gas heat exchanger with their connecting lines are totally designed in the same shape and arranged identically, nevertheless there is a risk of uneven Mass flow distribution of the synthesis gas in the two Trains. Will this imbalance of the mass flows not Corrected the beginning, then it increases Skew during operation. This can cause the system to fail and thus lead to the shutdown of the system.
  • the raw gas-clean gas / raw gas nitrogen (inert gas) heat exchanger and the lower connecting lines with heating provided to prevent it from preheating and / or approach to falling below the dew point in the Attachments can come.
  • the heating can be electrical Be kind; it is activated during start-up and switched off during stable operation.
